((11. 16-149) This inventionrelates to a hinge structure. The invention is more particularlyconcerned with a hinge structure for the removable pivotal connection ofan inner frame with a fixed outer frame and which hinge structure isparticularly characterized in facilitating the ready mounting anddismounting of the inner frame.

While the improved hinge structure is'not limitedin its adaptation it isof particular use in the pivotal connection of an inner sash or screenframewith an 'outer fixed frame, such as in awning type andcasement typeis ivoted to the upper horizontal side of thefixed frame,

whereas in the easement type window the sash frame is pivoted to avertical side of the fixed frame.

the room.

Both screen frames and storm window frames have to provide a hinge bythe use of which the' above noted objections are wholly overcome.

A further object of the invention is the provision of a hinge embodyinga pair of cooperating members, one

of which is adapted for pivotal connection with a fixed outer frame andis removably engageable with an inner frame, and the other of which isadapted for pivotal con nection with the inner frame and for contactwith the first member for holding same in operative engagement with theinner frame.

Other objects and advantages of the invention will be come apparent inthe course of the following detailed description, taken in connectionwith the accompanying drawings, wherein Fig. 1 is a side elevationalview of the hinge member adapted to be pivotally mounted on the outerframe.

Fig. 2 is a front elevational view of the hinge member adapted to bepivotally mounted on the outer frame.

Fig. 3 is a plan view of the hinge member adapted to be pivotallymounted on the outer frame as observed from the top of Fig. 1.

,less steel, and such stamping includes a generally rectangular body 12which is outwardly offset adjacent one end and one side thereof asindicated at 13 and thence continued in the form of an ear 14 which isprovided with i an aperture 15 which is outwardly countersunk asindieated at 16.

The-said body 12 is provided at said one side thereof with a rightangular rectangular extension 17 which is inwardly'slit at 18 and thefreed portion is bent into spaced parallel relation with the body 12 inthe form of a pointedtongue 19.

The hinge member 10 is adapted for pivotal connection with an outerfixed frame F of a casement-type window (Fig. 12) or with the outerfixed frame F of an awning-type window (Fig. 10).

In the casement-type window of Fig. 12 a hinge member 10 is pivotallyconnected to the upper and lower horizontal parts of the frame adjacentcorners at one side of the frame.

As is indicated more particularly in Figs. 7 and 9, the offset ears 14are disposed in said corners and pivotally connected to the frame bymeans of screws s (Fig. 8) and since the main body portions 12 areoffset with relation to said ears same will be in spaced relation to theframe for free swinging movement of the hinge members 10 about thescrews s.

The inner swingable frame is designated 1 in Fig. 12 and f in Fig. 10and same may be formed of stainless steel and adapted for supporting ascreen or a storm sash.

As is indicated in Fig. 13 the frame f is provided with a hole hadjacent each corner corresponding to the corners of the fixed frame inwhich the members 10 are swingably supported and the frame fis furtherprovided J the members and 11 are of stainless steel with a tapped hole11 adjacent each hole-h'--for a-purpose same may be left on boththeouter frame and inner later to appear. frame when the latter is not inuse and by the provision It is of course to be understood that frame fis also 7. of the novel two-part hinge the inner frame is capableprovided with holes similar to holes hand h but di'sposed"-ll of beingquickly and easily pivotally connected to the in the upper ends of itsvertical stiles. p outer frame.
